Mobile MOBA Vainglory lands big-time sponsors Amazon and Nvidia for its season finals

League of Legends and Dota 2 get all of the attention, but a different kind of competitor is also growing.

Vainglory told GamesBeat that Nvidia and Amazon will sponsor the season finals for the mobile multiplayer online battle arena (MOBA), which take place at the Esports Arena in Santa Ana, California, for North America and at the ESL Studio in Katowice, Poland for Europe.

MOBAs are one of the most popular kinds of game these days, largely because of their competitive and exciting esports scenes.

The top 20 nations alone will spend $83 billion on video games by the end of 2015, according to intelligence firm Newzoo. However, while the big dogs in the genre like League of Legends and Dota 2 are PC games, Vainglory is for mobile.
